Both notes, with a denomination of 20 yuan, feature the official emblem of the 24th Winter Olympics on the obverse.

两款纸币面值均为二十元，正面均印有第 24 届冬奥会会徽。

What Dr Gupta has shown, though in software rather than in the real, biological world, is that the obverse can also be true-changes in body morphology can optimise the way minds (or, at least, derls) work.

古普塔博士明，尽管是在软件中而不是在真实物世界中，相反情况也可能会发——形态改变可以优化大脑（或者至少是derl）工作方式。

If I understand the matter of all, science and art are the obverse and reverse of the Nature's medal; the one expressing the external order of things, in terms of feeling, and the other in terms of thought.

依我所见，科学和艺术实乃大自然这枚圣牌正反两面，一个以情感方式表达了事物外在规律，而另外一个则是一理性方式。
